NBN Affair: Turnbull Says AFP 'Act With Integrity'

Party Leaders addressed issues and plans amidst document leak saga.

Malcolm Turnbull says an AFP raid in Melbourne was made independently.

Prime Minister Malcolm Turnbull has defended the integrity of the Australian Federal Police after officers raided Labor figures in Melbourne as part of an investigation into the National Broadband Network.

Speaking on Saturday, Turnbull hit out at Labor for attacking the AFP over their handling of the matter.

"What they did was attack the integrity of the men and women of the Australian Federal Police that stand between us and many threats, many dangers," he told reporters on the NSW central coast.

Labor has claimed parliamentary privilege over the documents, some of which were seized from Senator Stephen Conroy's office.

Police reportedly can't access the documents until the Senate has resolved the privilege claim.

Opposition leader Bill Shorten said the PM was "deeply embarrassed" by ongoing problems with the broadband rollout.

"The Prime Minister is embarrassed by the revelations that his flagship project, the signature activity he has taken in public life as a politician, the NBN, I think he is deeply embarrassed ... that his incompetence is emerging," he said.

"The fact that the NBN he promised would cost $29 billion in 2013 is now costing $56 billion and climbing."

Shorten also addressed party faithful in southwest Sydney as the election campaign rolled on.

"This election should be about who has the best plans for Australian people and the future of our country," Shorten said in Campbelltown.

"We will fight this election to the families and small businesses of Australia on the real issues that make a practical difference in the lives of ordinary Australians."

The speech comes as Labor announced earlier today that it would appoint a LGBTI commissioner to the Australian Human Rights Commission, if elected on July 2.
